Fitness Tip: Don’t relax your abs as you lower your chest away from your knees during a crunch. You need to sustain the contraction on the way down.

Fitness Tip: Don’t avoid carbs. Your body needs them to fuel a workout, so reach for fruit or high-fibre crackers an hour beforehand and include some protein.

Fitness Tip: Add box jumps to your workout to improve your cardiovascular stamina and leg strength – you’ll really sculpt your hamstrings, quads and glutes.

Fitness Tip: Repeating the same workouts over and over with no variation is a surefire way to stop getting results.

Fitness Tip: When you run, breathe so that your belly rises as you inhale. This ensures that your lungs are inflating fully, so you’ll be able to go longer.
